P-toluenesulfonyl thiocyanide, also known as 4-methylbenzenesulfonyl thiocyanate, is an organic compound with the chemical formula C8H7NO2S2. It is a white crystalline solid that is soluble in organic solvents such as ethanol and acetone. p-toluenesulfonyl thiocyanide is primarily used as a reagent in organic synthesis, particularly in the preparation of various heterocyclic compounds and as a protecting group in peptide synthesis. It is also employed in the synthesis of pharmaceuticals and agrochemicals. Due to its reactivity, p-toluenesulfonyl thiocyanide should be handled with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

1200-84-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1200-84-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1200-84:
(6*1)+(5*2)+(4*0)+(3*0)+(2*8)+(1*4)=36
36 % 10 = 6
So 1200-84-6 is a valid CAS Registry Number.

REACTION OF 1,3-DIENES WITH ARYLSULFONYL THIOCYANATES

Tanaskov, M. M.,Starodub, P. E.,Stadnichuk, M. L.,Tanaskova, E. A.

, p. 1609 - 1615 (2007/10/02)

At room temperature arylsulfonyl thiocyanates add to conjugated dienes with the formation of 1,4-addition products.In all cases the organic sulfonyl radical is fixed at the least substituted carbon atom of the 1,3-diene system.In reaction with triethylamine or sodium ethoxide the adducts which form eliminate thiocyanic acid with the formation of conjugated dienyl sulfones.
